Application led January 23. 1926. Serial No. 83,222.

My invention relates to an improved and compact form of spray nozzle andhas particular application to such nozzles as are used in connectionwith the usual showerv bath equipment.

The objects of my invention are, among other things, to provide a noveland simplified form of nozzle of this type in whlch the mutuallyparallel individual streams or jets forced downwardly through theperforated discharge plate of the nozzle head are transversely cut anddeflected intermittently, thereby effectively breaking .up suchcontinuous discharge streams whereby an exhilerating and tonic effect isproduced on ythe skin of the batherfrom the individual lsub-dividedstreams in whichthe separate globules of water strike the body withrapid but intermittent succession.

With these and other objects in view my invention comprises the novelcombination, construction and arrangement of the varlous parts embodiedin my spray nozzle, and as hereinafter described and then particularlypointed out in the appended claims.

In thev drawings, Fig. 1 is an enlarged sectional `eleva ion of myimproved spray nozzle certain parts being-.broken away for the sake ofclearness;

Fig. 2 is a plan view looking upwardly in Fig. 1; and A Fig. 3 is asection taken on the line 3 3 of Fig. 1.

Similar numerals refer to similar parts throughout the several figures.

Referring to Fig. 1, the downwardly flaI'-, ing head 4 of my nozzle hassecured to its top the water inlet chamber 5 in which the water pipe(not shown)` may be screw threaded. Extending laterally from lthechamber 5 are two curved outlets 6 and 7 having their openings 8 and 9respectively projecting downwardly and directions'as shown in Figs. 1and AtfiXed to the lower end of the head 4 is the perforated dischargeplate 10 having suit-` in opposite so thatwater under pressure forcedfrom the chamber 5 through the curved outlets 6 y close parallelism withthe face of the plate 10 and extending to the outer rim thereof as shownin Figs. 1 and 2. The nut 19 threaded on the end of the shaft 15 holdsthe rotary stream-cutter 16 in place while the washer 20 spacestherotary stream-cutter 16 from the plate 10 as shown in Fig. 1.

In operationwater under pressure -fiows from the chamber 5 through thecurved outlets 6 'and 7 and forcibly impinges on the propeller blades 15causing the propeller v14 rapidly' to revolve and also diffusing thewater within the head 4. Such water is then discharged from the head 4through the orifices 11 in continuous streams or jets which areimmediately cut into intermittent finelydivided streams by thehorizontally-rotating arms 17 and 18 secured to the shaft 15 driven bythe propeller 14 as herei'nbefore described. s

It will be noted that the movement of the arms 17 and 18 is transverset0 the falling jets from the orifices 11. and. such arms in travellingacross such continuous streams effectively break up the jets so as topro-l duce finely-divided intermittent streams which then fall on thebody of the bather.

Various changes or modifications may be made in the form of the. s tructural elements embodied in my improved'isprajT nozzle withoutdeparting from the principle and scope of' my invention and withoutsacrificing its advantages.

I claim as my invention 1. A- spray nozzle comprising a head having asubstantially flat perforated discharge plate at one end, water outletswithin the head, a propeller actuated by water. issuing under pressurefrom said outlets, and a rotary water-cutting member actuated by saidpropeller in front of and in mutual parallelism with said dischargelate, whereby the jets from the discharge p ate are transversely cutby'said member. f

2. A spray nozzle comprising a head hav-v ing a substantially flatperforated dischar plate at one end, water outlets "within t e head, apropellerhaving a, series of blades actuated by water issuing underpressure from said outlets, and a rotary water-cutting member actuatedby said propeller in frontyof and in mutual arallelism with saiddischarge plate, whereby the jets from the discharge plate aretransversely cut by said member.

3. A spray nozzle comprising a head having an inlet chamber at the .topanda substantially flat perforated discharge plate closing -the bottom,a plurality of curved water outlets leading laterally from said chamberwithin the head, a propeller within the head having blades adapted to bedriven by Water under pressure from said outlets to rotate thepropeller, and a rotary member having fiat cutting arms arranged inparallelism with, and in front of, said discharge plate and revolublewith said propeller, whereby the jets from the dischargev plate aretransversely cut and intermittently deflected by said cutting arms.

4. Aspray nozzle comprising a head having an inlet chamber at the topand a substantially flat perforated discharge plate closing'the bottom,a plurality of curved water outlets leading laterally from said chamberwithin the head, a shaft journalled in said discharge plate, a propellermounted on said shaft within the head having blades adaptedv to bedriven by Water'under pressure from said outlets to rotate thepropeller, and a rotary member having flat cutting arms arranged inparallelism with, and in front of said discharge plate and mounted onsaid shaft and revoluble with said propeller, whereby the jets from thedischarge plate are transversely out and intermittently deflected bysaid cutting arms.

l 5. A spray nozzle comprising a head having an inlet chamber at the topand a circular substantially flat perforated discharge plate closing thebottom, a plurality of curved Water outlets leading laterally from saidchamber within the head, a shaft journalled in said discharge plate, apropeller mounted on said shaft Within the head having blades adapted tobe driven by water under pressure from said outlets to rotate thepropeller, and a rotary memberhaving radially disposed sector-shapedcutting arms projecting in promixity to the outer face of, andapproximately to, the outer rim of said discharge plate and inparallelism therewith, said member being removably securedvto said shaftand revoluble in unison with said propeller, whereby the jets from thedischarge plate are transversely Vcut and intermittently deflected bysaid cutting arms.

6. A spray nozzle comprislng a head having an inlet chamber at the topand a circularI substantially flat perforated discharge plate closingthe bottom, a plurality of curved water outlets leading laterally fromsaid chamber within the head, a shaft journalled in said dischargeplate, a propeller mounted on said shaft Within the head having bladesadapted to be driven by water under pressure from said outlets to rotatethe propeller, .and a rotary member having a pair of flat radiallydisposed, sectorshaped cutting arms projecting inproximity to the outerface of, and approximately to, the outer rim of said discharge plate andin parallelism therewith, said member being removably secured to saidshaft and revoluble in unison with said propeller, whereby the jets fromthe discharge platc are transversely cut and intermittently deflected bysaid cutting arms.
